Intended Use Raymarine DS400 and DS500 Digital Fishfinders are intended for recreational fishfinding. EMC Conformance All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: Raymarine equipment and cables connected to it are: At least 3 ft (1 m) from any equipment transmitting or cables carrying radio signals, e.g., VHF radios, cables and antennas. More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.

5 DS400 and DS500 Digital Fishfinders v Raymarine specified cables are used. Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual. If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position.

11 Chapter 1: Overview 1 Chapter 1: Overview 1.1 Introduction This handbook describes the DS400 and DS500 Digital Fishfinders. The DS400/DS500 feature state-of-the-art High Definition Fish Imaging (HDFI) technology. Constantly adjusting transmitter and receiver parameters, the DS400/DS500 intelligently analyzes fish and bottom echoes and automatically produces a crystal clear echo sounder display. D Figure 1-1: DS400 Digital Fishfinder D Figure 1-2: DS500 Digital Fishfinder

12 2 DS400 and DS500 Digital Fishfinders The DS400/500 employs a very high transmission repetition or ping rate which, along with the digital adaptive high sample rate receiver, ensures that fish and bottom structure are presented in superb detail and optimal color allocation. The DS400/500 digital bandwidth adaptation adjusts the receiver band width dynamically from very wide to very narrow, as required by the actual water conditions. This provides superior fish and bottom detection in conditions where other fishfinders see very little or nothing at all.

17 Chapter 2: Installation Selecting the Equipment Location Mounting Location The DS400/500 is waterproof to IPX7 is and designed to be mounted either above or below deck. The unit should be protected from physical damage and excessive vibration. CAUTION: Mount the DS400/500 in a protected area away from prolonged exposure to rain, salt spray, and direct sunlight, but well ventilated. When planning the installation, the following should be considered to ensure reliable and trouble free operation: Access: There must be sufficient space below the unit to enable cable connections to the panel connectors, avoiding tight bends in the cable. Interference: The selected location should be far enough away from devices that may cause interference, such as motors, generators, and radio transmitter/receivers (see the EMC guidelines earlier in this section). Magnetic compass: Mount the unit at least 3 ft (1m) away from a magnetic compass. Cable runs: The unit must be located near a DC power source. The power cable supplied is 5 ft (1.5 m), but a longer cable can be used if desired. Refer to Section 2.4. The maximum length of cable between the fishfinder and the transducer unit should not normally exceed 25 ft (8 m). If you need to use a longer cable, refer to Section 2.4. Environment: Good ventilation is required to prevent the unit from overheating. WARNING: Removal of the transducer cable from the DS400/500 while power is turned on can cause sparks. As with any electronic device, be sure the fishfinder is mounted where it is well ventilated and free from gasoline fumes.

18 8 DS400 and DS500 Digital Fishfinders 2.4 Cable Runs Consider the following before installing the system cables: You will need to attach the power and transducer cables. All cables should be adequately secured, protected from physical damage, and protected from exposure to heat. Avoid running cables through bilges or doorways, or close to moving or hot objects. Sharp bends must be avoided. Where a cable passes through an exposed bulkhead or deckhead, a watertight feed-through should be used. Secure cables in place using tie-wraps or lacing twine. Coil any extra cable and tie it out of the way. You will need to run the following cables: Power/NMEA cable, supplied with the unit. This 5 ft (1.5 m) cable has a connector plug at one end for connecting to the fishfinder, and 3 wires at the other end for connecting the power supply. The power cable may be extended by up to 60 ft (20 m) using a wire gauge of AWG 12 or greater. The DS400/500 is intended for use on the boat s DC power systems rated from Volts DC (13.8V nominal). Transducer cable, supplied with the transducer. This 25 ft (8 m) cable has a connector plug (with an outer nut that you must attach) at one end for the display unit or extension cable. The transducer cable may be extended up to a maximum of 60 ft (20 m) using optional extension cables. Cutting the transducer cable will severely reduce sonar performance: Do not cut the transducer cable or remove the connector. Do not shorten or splice the cable. If the cable is cut, it must be replaced it cannot be repaired. Cutting the cable will also void the warranty.

21 Chapter 2: Installation Mounting the Fishfinder The DS400/500 can be mounted on a dash, chart table, bulkhead, or deckhead using the supplied hardware. The unit can also be flush mounted directly into the console. Bracket Mounting To mount the DS400/500 on the supplied bracket: 1. Loosen the knobs and remove the mounting bracket from the unit. 2. Mark the locations of the mounting bracket screw holes on the mounting surface. 3. Drill 5/16" (7 mm) holes through the mounting surface at the marked locations. 4. Align the mounting bracket holes with the holes on the mounting surface. 5. Use the screws and nuts supplied to attach the mounting bracket to the mounting surface at the marked locations. 6. Attach the unit to the mounting bracket, adjust the display angle, and tighten the knobs. Console Mounting (optional) The fishfinder may also be installed directly into the console. This requires the purchase of an optional Flush Mount kit, Raymarine part number E66067 (for DS400) or E66068 (for DS500). To flush mount the unit directly into the console using the optional kit: 1. Make sure there are no hidden electrical wires or other items behind the location before proceeding. Make sure there is sufficient rear access for mounting and cabling. 2. Check the selected location for the unit. A clear, flat area is required. DS400: allow at least 5½" (140mm) wide by 4¾" in (120mm) high, with at least 3½" (89mm) of clearance behind the panel. DS500: allow at least 6¾" (171 mm) wide by 6¼" (159mm) high, with at least 3½" (89mm) of clearance behind the panel. 3. Using the template supplied at the end of this handbook, trace out the unit opening and four mounting screw locations. 4. Use a 3-5/8" hole saw to cut the hole through which the circular rear of the unit will pass.

22 12 DS400 and DS500 Digital Fishfinders 5. Remove the mounting bracket knobs, bracket and mounting frame from the unit. Make sure that the unit fits in the cut-out area. 6. Drill four 3/16 in (5 mm) holes as indicated on the template. 7. Hand tighten the studs into the holes provided at the rear of the unit. 8. Connect the Power/NMEA cable and transducer cables to the unit. Avoid tight bends in the cables. 9. Place the gasket on the unit and slide the unit into the panel cut-out. 10.

23 Chapter 2: Installation System Connections The rear of the display unit provides the following connection sockets: Transducer connection. Power, for 12 VDC power connection and NMEA connection. D Transducer Power/NMEA Figure 2-5: DS400/500 Connector Panel The following sections detail the connectors used when installing the DS400/500. DC Power Connection The DS400/500 is intended for use on the boat s DC power systems rated from Volts DC (13.8V nominal). The power connection to the unit should be made at either the output of the battery isolator switch, or at a DC power distribution panel. Raymarine recommends that power is fed directly to the DS400/500 via its own dedicated cable system. A 2 amp, fast blow fuse is attached (in-line) to the red (positive) wire. A 5 ft (1.5 m) Power/NMEA cable is supplied for connecting the boat s DC power to the unit. The Power/NMEA cable may be extended by up to 60 ft (20 m) using a wire gauge of AWG 12 or greater. DC power is connected at the seven-pin Power/NMEA connector on the unit s connector panel. The connector (viewed from the outside) and pin functions are shown in the following diagram and table. f pin1 D6462-1

A fast blow 2 amp fuse is installed in-line on the red (positive) wire. CAUTION: If the power connections are accidentally reversed the system will not work. Use a multimeter to ensure that the input power leads are connected for correct polarity. Transducer Connection A 25ft (8m) cable is supplied with the transducer. The transducer cable connector has a nut that has been removed to aid installation. To enable you to complete the installation without cutting the cable, ensure that any holes you drill are large enough to accept the connector, with the nut removed (approximately 13/16" or 21 mm). Before attaching the transducer cable, you will need to attach the connector nut, which is included in the transducer packaging. The transducer cable is attached to the 7 pin male TRANSDUCER connector on the connector panel of the DS400/500. (See Figure 2-5.) CAUTION: Do not pull on the cable. This can damage the transducer wires. Do not cut the transducer cable or remove the connector. Do not try to shorten or splice the cable. Cutting the transducer cable will severely reduce sonar performance.

25 Chapter 2: Installation 15 If the cable is cut, it must be replaced it cannot be repaired. Cutting the cable will also void the warranty. WARNING: Removing the transducer cable from the rear of the DS400/500 while the fishfinder is powered on can cause sparks. Only remove the transducer cable after power has been removed from the DS400/500. If the transducer cable is accidentally removed while the DS400/500 is powered on, remove power from the fishfinder, replace the transducer cable, and then restore power. As a safety feature, the DS400/500 only recognizes that the transducer is connected at power-up.

26 16 DS400 and DS500 Digital Fishfinders 2.7 Installing the E66062 (P58) Transducer Please use the following installation instructions if your fishfinder is equipped with a E66062 (P58) Multisensor Transom Mount Transducer. Installation instructions for other transducer models are included with the transducer. Please read these instructions completely before proceeding with the installation. CAUTION: NEVER USE SOLVENTS Cleaners, fuel, paint, sealants, and other products may contain strong solvents, such as acetone, which attack many plastics greatly reducing their strength. Applications Not recommended for boats with large or twin screw inboard engine(s) Requires 89mm (3-1/2") of headroom to install Good operation up to 44kts (50MPH) Vertically orients sound beam on hull with deadrise angle up to 30 Adjusts to transom angles from 2 22 Bracket protects multisensor from frontal impact only Tools and Materials Screwdrivers Pencil Safety goggles Dust mask Electric drill Drill bits: Bracket holes 4mm, #23, or 9/64" Fiberglass hull chamfer, countersink, 6mm, or 1/4" Transom hole (optional) 18mm, 11/16", or 3/4" Cable clamp holes 3mm or 1/8" Masking tape Marine sealant Straight edge Zip-ties Water-based antifouling paint (mandatory in salt water)

27 Chapter 2: Installation 17 Pretest Connect the multisensor to the instrument and spin the paddlewheel. Check for a speed reading and the approximate air temperature. If there is no reading or it is inaccurate, return the product to your place of purchase. D Figure 2-6: E66062 (P58) Multisensor Transducer Mounting Location For the best performance, the transducer must be in contact with aeration-free and turbulence-free water. Mount the transducer on the transom as close to the centerline (keel) of the boat as possible. On slower heavier displacement hulls, positioning it farther from the centerline is acceptable. Do not mount in an area of turbulence or bubbles: Near water intake or discharge openings Behind strakes, struts, fittings, or hull irregularities Behind eroding paint (an indication of turbulence) CAUTION: Avoid mounting the transducer where the boat may be supported during trailering, launching, hauling, or storage. Single drive boat Mount the transducer on the starboard side at least 75mm (3") beyond the swing radius of the propeller (see Figure 2-7 ). Twin drive boat Mount the transducer between the drives.

Insert the transducer s pivot posts into the recesses on the sides of the bracket (see Figure 2-8 ). 2. Press the two nuts into the slots in the back of the bracket. 3. Aligned the holes in the transducer, bracket, and nuts. Insert the two machine screws capturing the nuts. Tighten the machine screws until the transducer will stay in the up (released) position unaided. slot (2) pivot post (2) machine screws (2) nuts bracket recess (2) D Figure 2-8: Assembling the Transducer

29 Chapter 2: Installation 19 Marking and Hole Drilling 1. At the selected location on the starboard side of the hull, position the transducer, so the transducer projects 3mm (1/8") below the bottom edge of the transom (see Figure 2-10 ). 2. Being sure the bottom of the transducer is parallel to the waterline, mark the location of the screw holes with an X in the center of the two outer most slots. CAUTION: Always wear safety goggles and a dust mask. 3. Using a 4mm, #23, or 9/64" drill bit, drill two holes 22mm (7/8") deep at the locations indicated. To prevent drilling too deeply, wrap masking tape around the bit 22mm (7/8") from the point. Fiberglass hull Minimize surface cracking by chamfering the gelcoat. If a chamfer bit or countersink bit is not available, start drilling with a 6mm or 1/4" bit to a depth of 1mm (1/16"). Plastic Shim Standard transom (13 transom angle) The bracket is designed for a standard 13 transom angle. The shim is not needed for this installation. Skip to Mounting the Bracket. Stepped transom and jet boats (3 transom angle) Use the shim with the tapered end down. Be sure the nuts are in the slots in the back of the bracket before applying the shim (see Figure 2-8 ). Small aluminum and fiberglass boats (20 transom angle) Use the shim with the tapered end up. Be sure the nuts are in the slots in the back of the bracket before applying the shim (see Figure 2-8 ). If you are unsure about using the shim, do one of the following: Measure the transom angle of your boat using a digital level or bubble level and protractor. Then follow the instructions above for your transom angle. Experiment with the shim by following the instructions Mounting the Bracket and Checking the Angle and Projection. Mounting the Bracket 1. Apply marine sealant to the threads of two, #10 x 1-3/4", self-tapping bracket screws to prevent water seepage into the transom. 2. Screw the transducer (with the shim if needed) to the hull (see Figure 2-10 ). Do not tighten the screws at this time.

30 20 DS400 and DS500 Digital Fishfinders Checking the Angle and Projection Do not position the bow of the transducer lower than the stern because aeration will occur. Do not position the transducer farther into the water than necessary to avoid increasing drag, spray, and water noise and reducing boat speed. 1. Using a straight edge, sight the underside of the transducer relative to the underside of the hull (see Figure 2-9 ). The stern of the transducer should be 1 3mm (1/16 1/8") below the bow of the transducer or parallel to the bottom of the hull. 13 transom angle 3 transom angle 20 transom angle parallel angle angle reversed shim with taper down shim with taper up angle too steep slight angle slight angle slight angle Figure 2-9: Transducer Angle Adjustment D Using the vertical adjustment space in the bracket slots, slide the transducer up or down (see Figure 2-10 ). Be sure the bottom left corner of the transducer projections 3mm (1/8") below the bottom of the hull.

31 Chapter 2: Installation 21 cable cover cable clamp 50 mm (2") Hull projection 3mm (1/8") parallel to waterline D Figure 2-10: Vertical Adjustment and Cable Routing 3. When you are satisfied with the position of the transducer, tighten the two bracket screws. Testing on the Water 1. Become familiar with your fishfinder s performance at a speed of 4kts (5MPH). 2. Gradually increase the boat speed and observe the gradual decline in performance due to turbulent water flowing over the transducer s active surface. 3. If the degradation is sudden (not gradual), identify the boat speed at which the onset occurred. Return the boat to this speed, then gradually increase speed while making moderate turns in both directions. 4. If the performance improves while turning, the transducer s position probably needs adjustment. It is probably in aerated water. Move the transducer farther down into the water in increments of 3mm (1/8"). If the performance does not improve satisfactorily, move the transducer closer to the centerline of the boat. Fill unused screw holes with marine sealant.

32 22 DS400 and DS500 Digital Fishfinders High-speed operation (above 40MPH) may require less projection in the water to improve performance. Stabilizing the Bracket Stabilize the bracket by installing the third bracket screw at the bottom of the center slot (see Figure 2-11 ). Using a 4mm, #23, or 9/64" drill bit, drill a hole 22mm (7/8") deep. To prevent drilling too deeply, wrap masking tape around the bit 22mm (7/8") from the point. Fiberglass hull Minimize surface cracking by chamfering the gelcoat. If a chamfer bit or countersink bit is not available, start drilling with a 6mm or 1/4" bit to a depth of 1mm (1/16"). Apply marine sealant to the threads of the #10 x 1-3/4" self-tapping screw to prevent water seepage into the transom. Tighten the screw. D Figure 2-11: Stabilizing the Bracket Cable Routing Route the transducer cable over the transom, through a drain hole, or through a new hole drilled in the transom above the waterline. Never cut the cable or remove the connector; this will void the warranty. CAUTION: Always wear safety goggles and a dust mask. 1. If a hole must be drilled through the transom, choose a location well above the waterline (see Figure 2-10 ). Check for obstructions such as trim tabs, pumps, or wiring inside the hull. Mark the location with a pencil. Drill a hole using the appropriate size bit to accommodate the connector. 2. Route the cable over or through the transom.

33 Chapter 2: Installation On the outside of the hull, secure the cable against the transom using the cable clamps. Position a cable clamp 50mm (2") above the bracket and mark the mounting hole with a pencil. 4. Position the second cable clamp halfway between the first clamp and the cable hole. Mark this mounting hole. 5. If a hole has been drilled in the transom, open the appropriate slot in the cable cover. Position the cover over the cable where it enters the hull. Mark the two mounting holes. 6. At each of the marked locations, use a 3mm or 1/8" bit to drill a hole 10mm (3/8") deep. To prevent drilling too deeply, wrap masking tape around the bit 10mm (3/8") from the point. 7. Apply marine sealant to the threads of the #6 x 1/2" self-tapping screws to prevent water from seeping into the transom. If you have drilled a hole through the transom, apply marine sealant to the space around the cable where it passes through the transom. 8. Position the two cable clamps and fasten them in place. If used, push the cable cover over the cable and screw it in place. 9. Route the cable to the instrument being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the transducer cable from other electrical wiring and the engine(s). Coil any excess cable and secure it in place with zip-ties to prevent damage. 10. Connect the transducer to the transducer connector on the rear of the fishfinder. Checking for Leaks CAUTION: When the boat is placed in the water, immediately check for leaks around the screws and any holes drilled in the hull. Never install a transducer and leave the boat in the water unchecked for several days.

34 24 DS400 and DS500 Digital Fishfinders Operation and Maintenance Releasing the transducer The transducer releases easily when it is fastened to the hull. Give a sharp blow to the bottom of the transducer using the palm of the hand. CAUTION: Never strike the transducer with anything except the palm of the hand. Never strike the paddlewheel Antifouling Paint Marine growth can accumulate rapidly on the transducer s surface reducing performance within weeks. Surfaces exposed to salt water that do not interlock, must be coated with anti-fouling paint. Use water-based antifouling paint only. Never use ketone-based paint, since ketones can attack many types of plastic possibly causing damage to the transducer. Apply paint every 6 months or at the beginning of each boating season. Cleaning Clean the transducer with a soft cloth and mild household detergent. If fouling occurs, use a stiff brush or putty knife to remove the growth being careful to avoid scratching the transducer s face. In severe cases, wet sand the paddlewheel with fine grade wet/dry paper. Servicing the Paddlewheel If the paddlewheel becomes fouled or inoperable, remove it for cleaning. Remove the cover by depressing the latch near the paddlewheel. Using a small finish nail, push the shaft out. (see Figure 2-12 ).

37 Chapter 3: Getting Started 27 Chapter 3: Getting Started 3.1 Introduction This chapter provides basic instructions to get you started using the DS400/ 500 Digital Fishfinder. It describes Simulator mode and can help you to become familiar with the basic functions of the fishfinder s operation controls. More detailed information on using the menu items and display controls is provided in Chapter 4 and Chapter 5, respectively. 3.2 Powering on the Fishfinder PWR Connect the power cord to boat s power source and plug into the power port on the connector panel. Press the PWR button on the DS400/500. Details on setting up your DS400/500 and display are given in Chapter Simulator Mode If you have not fully installed the fishfinder, you can still operate in Simulator mode by connecting the fishfinder to a 12VDC power supply. Figure 3-1 demonstrates how to setup the DS400/500 for Simulator mode. Attach the red wire from the power lead to positive (+) and the black wire to negative ( ). When you power up the DS400/500 without connecting the transducer, the unit enters Demo mode. This provides a preprogrammed demonstration highlighting the fishfinder s main features. This function enables you to practice operating the fishfinder without data from the transducer, using simulated data. If the transducer is connected, you can enter Simulator Mode by following instructions outlined on page 74.

38 28 DS400 and DS500 Digital Fishfinders Fishfinder Red Black DC Volts D Figure 3-1: Demo/Simulator Mode Setup 3.4 LCD Display When you first switch on the fishfinder, the scrolling bottom graph, or Fishfinder Page, is displayed. This is a graphical representation of the echoes seen by the DS400/500. As time passes, this display scrolls from right to left and becomes a record of the echoes seen. A typical display is shown in Figure 3-2. The images at the right hand side of the display are the most recent echoes. Some echoes indicate fish, and others show the bottom. It can also indicate bottom structures, such as a reef or shipwreck. The upper and lower depth range limits are shown. You can customize the sounder by choosing what is displayed and how it is displayed (including language and units). For example, you can set whether the bottom graph display scrolls and you can select the range to adjust the depth displayed. You can view the cursor position and a variety of data (such as speed and depth) from the transducer and other equipment in user-selectable data boxes. These data boxes can be moved around the screen and they can be switched on or off. Chapter 5 includes details on adjusting the display, other set up options are described in Chapter 6.

Use the trackpad keys to scroll through the sub-menus. 3.8 Interpreting and Adjusting the Sounder Image The DS400/500 uses sound waves to find fish and show the bottom of a lake or sea. The transducer sends high-frequency sound waves into the water; these sound waves strike fish, the bottom, or other objects in the water and return as echoes. The DS400/500interprets these echoes to present an image of the fish and bottom. The strength of echoes is indicated by different colors. You can use this information to determine the size of fish and the bottom structure. Other objects in the water, such as debris and air bubbles, also return echoes; these echoes are generally weaker than the fish or bottom echoes and produce background noise or clutter on the display. The digital sounder provides controls to reduce the background noise and to adjust the way in which echoes of different strengths are displayed.

48 38 DS400 and DS500 Digital Fishfinders Fish Indications When the sounder detects a fish, it displays an arch-shaped mark. In general, a larger arch indicates a larger fish, though this rule is not always true. Let s say that there are two fish of the same size: one is close to the surface, the other is near the bottom. The fish which is close to the surface has a larger arch because, being closer, more sound waves get returned to the fishfinder. To display the depth of the fish, switch on the TARGET DEPTH ID from the menu, as described on page 58. The sound waves are actually reflected by the swim bladder near the center of the fish, not by the body of the fish. The size of this swim bladder is different for different kinds of fish and this can affect the size of fish arches on the image. A fish with a large swim bladder produces a large fish arch, while a fish with a small one produces a small arch. Several arches together show a school of fish. Figure 3-6 illustrates some typical fish indications. An arch-shaped image indicates a fish. 50 khz The same fish appears differently when shown by the 50 khz or 200 khz transducer beams. 200 khz A shallow arch is generated when the the boat is moving slowly. This indicates a group of small fish. A fish moving under a stopped boat shows as a line. When the boat is moving very fast, a fish appears as two parallel lines. D Figure 3-6: Fish Indications Effect of Frequency and Boat Speed The return from a fish has a different appearance depending on the frequency used: 50kHz produces a wide beam, so a fish spotted by this frequency gives a broad arch; the 200 khz beam is narrower so the same fish produces a narrower arch.

49 Chapter 3: Getting Started 39 The shape of the arch is also affected by the speed of the boat. If the boat is moving slowly, the arches tend to be longer; if the boat is moving more quickly, the arches are short and peaked. If the boat is moving very fast, a fish may be indicated by vertical lines. 3.9 Using the Variable Range Marker (VRM) QUIT The VRM (variable range marker) key is used to determine the distance behind the boat of an object on the display. The VRM function is available on the scrolling sonar display and zoom windows, if your transducer is equipped with a paddlewheel for measuring speed and distance. To display the VRM, press ENTER from the main fishfinder page. The VRM is displayed as a vertical line running the entire height of the display. You can use the < and > keys of the trackpad to move the VRM over a particular object to reference it from the boat. Distance behind the boat is displayed next to the vertical line. The VRM distance units correspond to the depth units assigned in the system set up parameters you have assigned for your unit. However, when set to fathoms, the VRM is displayed in feet. The vertical line does not scroll with the scrolling sonar image. If the display range changes, the VRM retains its position. When you switch on the VRM, it is displayed at its last position. Press QUIT to remove VRM from the screen. If the sounder is in split frequency display mode, the VRM is shown in only one window at a time.

Note: The PAUSED setting doesn t stop sonar pinging. Digital depth continues to be calculated while scrolling is paused. The default is ON. Range By default, the sounder automatically adjusts the display range, selecting the shallowest range that keeps the bottom in the lower half of the display window. Alternatively, the Range setting enables you to select the maximum depth displayed on the scrolling bottom and A-Scope displays. This parameter determines whether the depth range displayed is set automatically by the sounder or manually using the Trackpad. AUTOMATIC for the sounder to determine the range as dictated by the current depth. Select MANUAL to enable the Trackpad for setting the range. If you press the Trackpad to manually set the range while the automatic setting is enabled displays, the fishfinder displays the following message:

The following range/shift values are available: Table 4-2: Range Values Feet Fathoms Meters (CE models only)

55 Chapter 4: Menu Operation 45 Hunt Mode The DS400/500 features a digital Hunt mode that automatically searches for the bottom while the sounder is in Auto Range. If bottom cannot be determined while AUTO RANGE is selected, the DS400/500 pings the last known depth, and then incrementally increases the ping depth until the bottom is found. If bottom is not found, the sounder returns to the original depth and repeats the process. If AUTO FREQUENCY is also selected (see the section describing Frequency on page 45) when the sounder completes the auto range hunt process, the process is repeated in the other frequency. If MANUAL FREQUENCY is selected, hunt mode only continues in the selected frequency. This process continues until bottom is detected or you switch to manual range mode. The maximum depth to which Hunt mode searches is as follows: 200 khz 500ft (150m) 50 khz 2000 ft (600m) For example, let s say a DS400/500 is set for auto range & auto frequency and bottom is currently detected at 250 ft using 200 khz. The bottom signal becomes lost, so the sounder switches to Hunt mode. Pinging begins at 250 ft (the lastknown good depth) using 200 khz and increments to 500 ft. If bottom is not detected, the sounder switches to 50 khz, repeats pinging at 250 ft, and increments up to a maximum of 2000 ft. If bottom is still not detected, the DS400/500 returns to 250 ft using 200 khz to continue the process. When bottom is found, Hunt mode ceases and the sounder adjusts to the range and frequency appropriate for the new depth. The default setting is AUTOMATIC. Frequency The DS400/500 uses dual frequency sonar 50 khz and 200 khz and can be used in either auto or manual modes. The DS400/500 can automatically select the appropriate frequency, based on the current display range. As the depth increases while in Auto Frequency mode, the fishfinder shifts from 200 khz to 50 khz. As the depth decreases, the fishfinder switches from 50 khz to 200 khz. You can select the transducer frequency for automatic or manual operation at 50 khz, 200 khz or both frequencies simultaneously.

56 46 DS400 and DS500 Digital Fishfinders AUTOMATIC enables the digital fishfinder to determine the optimum frequency based on the current conditions. 200 khz MAN fixes the frequency at 200kHz no matter what depth you are viewing. This frequency is typically used for shallower water and a more detailed view. When using this frequency, the transducer scans a narrower area, but produces a more detailed view. The 200 khz signal is good for finding fish near the bottom or close together. It is better for use in shallow water. 50 khz MAN fixes the frequency at 50kHz no matter the depth. This frequency is typically used for wide coverage and deep water. When using this frequency, the transducer scans a wide area. The 50 khz signal penetrates water well, so is good for use in deep water. DUAL MAN displays separate screens for both 50 and 200kHz. The transducer can operate in both 50 khz and 200 khz frequencies at the same time. If you choose dual frequency operation, the scrolling bottom display is split vertically; the left half shows the 200 khz detailed view and the right half shows the 50 khz image. The default setting is AUTOMATIC. A-Scope Use the A-Scope screen to show raw sonar data directly from the transducer beam. This gives you a real time image of fish and bottom structure directly below the transducer. This function is very useful in showing the strength of the echo returned from a fish. The display is split vertically, with the A-Scope image in the right hand window and the scrolling bottom image in the left hand window. Select one of the three modes for A-Scope, as demonstrated in Figure 4-2 : OFF, in which A-Scope does not appear. ON-1, in which the image takes up the entire A-Scope window. ON-2, in which only the left side of the image displayed in Mode ON-1 expands to the entire A-Scope window. This mode provides the greatest resolution. ON-3, in which the A-Scope image is angled outward as the signal width (indicated with dotted lines) increases with depth. The default setting is OFF.

57 Chapter 4: Menu Operation 47 A-SCOPE Mode ON-1 Mode ON-2 Mode ON ft D Figure 4-2: The Three Modes of A-Scope GAIN MODE... The sounder provides GAIN controls to reduce background noise and determine how different strength echoes are shown. Automatic adjustment of each of these parameters is available or you can manually adjust the settings using the trackpad. Note: Automatic Gain settings take advantage of the hardware s advanced digital technology. As a result, the sounder typically performs better in automatic mode than manual. For better performance Raymarine recommends selecting AUTO mode for all Gain options. Note that this menu item is in all caps and in followed by an ellipsis (...). This is an indicator that the setting contains sub-menus. Gain Mode is comprised of seven sub-menus. Gain Color Gain Time Variable Gain (TVG)

58 48 DS400 and DS500 Digital Fishfinders Sounder Interference Rejection (Int. Rej.) Second Echo Rejection Power Maximum Ping Rate Use the trackpad to scroll through the sub-menu items. To set a Manual Gain value in any of the following sub-menus: 1. Use the trackpad to highlight MANUAL. 2. Press ENTER. Normal (not highlighted) text appears. 3. Press the or > Trackpad key to increment and the or < Trackpad key to decrement the Gain setting. 4. Press ENTER to accept the MANUAL value. GAIN The gain, or sensitivity, of the display adjusts background noise by varying echo strength for display. The value of the gain control determines the strength above which echoes are displayed. If the gain is low only the strongest echoes are displayed. As the gain is increased, weaker echoes (from air bubbles, for example) are also displayed. The automatic gain modes find the ideal sensitivity level for you, based on depth and water conditions. Automatic gain modes take advantage of the hardware s advanced HDFI technology. As a result, the sounder typically achieves a sharper image in any of the automatic gain modes than is possible in manual mode.automatic gain varies the gain throughout the water column based on the current conditions. The DS400/500 provides three pre-defined automatic gain settings: AUTO FISHING is the highest automatic gain setting. It gives the best details of the targets you have located and is ideal for slow speeds and drifting. AUTO TROLLING is a medium gain setting that is better suited for trolling speeds. AUTO CRUISING is the lowest automatic gain setting, ideal for reducing background noise or travelling to your fishing spot at high speeds. MANUAL gain should be set high enough to see fish and bottom detail but without too much background noise. Generally, a high gain is used in deep and/or clear water; a low gain in shallow and/or murky water. The default setting is AUTO FISHING.

59 Chapter 4: Menu Operation 49 Color Gain Color Gain determines how echoes of different strengths are displayed. 128 colors per palette are available, with the strongest signals displayed in colors representing the strongest signals in the currently-selected palette. The Color Gain control sets the lower limit (threshold) for the strongest signal and is represented as a percentage of that strongest signal. A lower Color Gain percentage means a stronger echo is required to be displayed in the strongest signal colors. All echoes with a signal strength above this value are displayed in darker colors. All echoes weaker than this value are divided equally between the remaining colors. Your choices are: AUTOMATIC: Displays colors based on current conditions (with as many colors as possible) while minimizing noise and clutter. As conditions change the auto-color gain adjusts. MANUAL: Setting a low value produces a wide band for the weakest colors but a small signal band for the other colors; setting a high value gives a wide band for the strongest colors but a small signal band for the other colors. If you select manual adjustment, you will need to re-adjust the gain as conditions change. The default setting is AUTOMATIC. Time Variable Gain (TVG) TVG (Time Variable Gain) reduces clutter by varying the gain throughout the water column. This function is useful for reducing noise that can appear. Increasing the TVG value increases the maximum depth to which TVG is applied. Decreasing reduces the maximum depth. Although you can manually set the TVG level, Raymarine recommends letting the unit choose the proper level for you by selecting AUTOMATIC. The default setting is AUTOMATIC. Sounder Interference Rejection (Int. Rej.) Two or more sonar-equipped vessels operating within range of each other can interfere with sounder operation. This usually appears as vertical streaks on the display that do not represent actual targets. This option can reduce such interference, either manually or automatically. AUTOMATIC selects the best rejection level for you

60 50 DS400 and DS500 Digital Fishfinders LOW minimizes rejection of potential interference. Use this setting when you want to be sure that what has been removed are really false returns. HIGH rejects much more interference but can potentially weaken the appearance of actual targets. The default setting is AUTOMATIC. Second Echo Rejection A so-called second echo can caused by the sonar signal returning from the bottom, reflecting off the water s surface, bouncing off the bottom again and returning. This option helps eliminate identifying a false bottom. Select from the following: OFF, which offers no rejection LOW, which provides minimal rejection by slightly reducing the ping rate HIGH, which offers the greatest signal rejection by decreasing the ping rate further The default setting is LOW. Only set this setting to HIGH if you notice second echoes appear on your display. Power The Power setting provides adjustment of the transducer signal. Select from the following: AUTOMATIC, in which the sounder automatically determines the optimal power setting based on the current depth, speed, and (bottom) signal strength MANUAL, in which the power is increased or decreased in 10% increments. The default setting is AUTOMATIC. Max. Ping Rate The setting determines the maximum number of sonar pulses, or pings, the transducer emits per second. You can set Max Ping Rate anywhere between 5 30, in increments of 1. The default setting is 30 pings per second, the maximum. You can reduce this number down to a minimum of 5 pings per second, if necessary, to help reduce second echoes.

61 Chapter 4: Menu Operation 51 ZOOM... Zoom enlarges all or part of the scrolling bottom display at x2, x3 or x4 magnification. You can select automatic zoom so the sounder keeps the bottom in the lower portion of the zoom window or manually pick the area to be zoomed. The ZOOM sub-menus are: View Zoom magnification Zoom Mode View The View sub-menu determines how the zoomed area appears on the screen. OFF means the display is not zoomed. SPLIT means the display is split vertically, with the zoom image in the left hand window and the scrolling bottom display in the right hand window. See Figure 4-3. In a split window display, a zoom box appears, representing the range being displayed in the zoom window.

GRAY COPPER NIGHT VISION Background Color When the CLASSIC Palette is selected, you can also choose the background color used. Three colors are available for the sonar display background black, white and blue. You will probably find that you need to change the background color in different light conditions. For example, a white background is probably easiest to see in bright sunlight, but a black background may be preferable at night.

This menu group is used to set up alarms that are available to alert you of certain conditions. Each alarm can be toggled ON and OFF and you set the threshold at which the alarms are triggered, except for the fish and battery voltage alarms. Alarms consist of an audible tone and moving arrows pointing to the data display for that particular item. When an alarm is activated, press a key to mute the tone. The visual indicator continues as long as the condition exists. 40 Figure 6-2: ft Alarm Condition 60 D DEPTH ALARM Indicator (scrolling) You may want to use the shallow and deep water alarms when you are anchored. Set the limits to just above and below your anchor depth; the sounder triggers an alarm if the anchor drags and the boats moves into shallower or deeper water.
